What is the height of the geostationary orbit form the surcface of the earth?

The height of geo-synchronous orbit from the surface of the earth is

Calculate the height of a geostationary satellite.

what is a stationary orbit ?

Find the gravitational potential at the site of a geostationary satellites . Assume the height of the satellite to be 4200 km from the centre of Earth. (Mass of Earth =6.0xx10^(24)kg) .

A space station is at a height equal to the radius of the Earth . If v_E is the escape velocity on the surface of the Earth , the same the spastation v_E
